No, not with LVD (or real/HV differential), at least not if you stick to
using components within the required specifications (not all off-the-
shelf SCSI components deserve the name, particularly in PC circles).
Your claim is only true for non-differential Ultra-II (or is it III?)
FAST SCSI where the minimum inter-device spacing and the bus length
limits force you to restrict your bus to only four such devices.
It's also never been wise to mix FAST, Ultra-FAST, and/or Ultra-*-FAST
devices on the same bus, especially if it's not a differential bus.
(though why anyone would ever use anything but differential signalling
is beyond me! ;-)
